Piledriver (sex position)

The piledriver is a sexual position. Named after the downward motion of an actual pile driver, the position is executed by the receiving partner lying on their back bent into a frontbend in a pose similar to the yoga plow pose, with their bottom up and their legs bent over their head, while the insertive partner stands above them and inserts their penis or other object downwards into the receptive partner's vagina or anus.

The position is both acrobatic, and quite strenuous for both participants, in particular the receptive partner, who is severely constrained by the frontbend.
